5.5 Installing Power Box

Mount the power box onto a wall or metal surface. Secure it via its buckles. Install the guide rail for the power box, ensuring it is 200mm away from the Logger1000. Tilt the power box and hook its buckle into the guide rail, pressing down until it clicks into place.

6 Electrical Connection

6.1 Safety Instructions

Ensure all cables are intact, well-insulated, appropriately dimensioned, and firmly connected to prevent device damage or personal injury.

6.2 Port Introduction

External wiring terminals are located at the bottom of the Logger1000. Key ports include:

6.3 Connection to PV Devices

The Logger1000 connects to inverters, Smart Energy Meters, and Meteo Stations.

6.3.1 Connection to a single inverter

RS485 terminal block connection: Use shielded twisted pair cable (0.75mm²-1.5mm²). Connect RS485 A to port A and RS485 B to port B. Ensure shielding is single-point grounded. Use euro-style terminals for multi-strand wires.

6.3.1.2 RJ45 port connection

Use shielded twisted pair Ethernet cable. For shielded Ethernet cable, wire 3 (white-green) is RS485-B, and wire 6 (green) is RS485+A. Connect to the RS485 ports.

6.3.2 Connection to multiple devices

Connect multiple inverters in RS485 daisy chain. For over 15 devices, use a 120Ω terminal resistor. The Logger1000 supports up to 3 RS485 buses and 30 devices. Ensure unique addresses and consistent serial port parameters (baud rate, data bit, stop bit, check bit) for all devices on a bus.

6.3.3 Connection to Smart Energy Meter

Recommended meters comply with DL/T645 or Modbus protocol. Connection can be via RS485 or Ethernet. For RS485, connect communication cable to Logger1000's RS485 port. For Ethernet, use Ethernet cables to connect the meter to a core switch, and the Logger1000 to the same switch, or directly connect meter to Logger1000 if no switch is present. CAT 5E or higher is recommended.

6.3.4 Connection to Meteo Station

Connect via RS485 port or AI port. For RS485, connect the communication cable. For AI, connect the communication cable to the AI port. If connecting multiple devices including Meteo Station, place the Meteo Station at the end of the daisy chain.

6.4 Connection to Background

Connect to the PV system background via the network port using Modbus TCP or IEC104 protocol. The Logger1000 acts as a slave device. Connect via Ethernet switch/router or directly with a network cable. Default IP for ETH is 12.12.12.12.

6.5 Connection to Micro-SIM

Supports hot-plugging of Micro-SIM cards (12mm x 15mm).

6.6 Connection to Power Box

The Logger1000 supports DC24V power supply. Connect DC cable to "24V IN" and "24V OUT" ports. Connect grounding cable. Connect the DC cable from the power box's "DC 24V OUT" to Logger1000's "24V IN". Connect AC cable to the power box's "AC (100~277V)" port.

6.7 Cable Routing Requirements

Route communication cables away from power cables, forming a right angle at intersections. Maintain a distance of over 200mm between parallel shielded communication cables and power cables. Cables should be routed as close to ground surfaces or supports as possible.

7 Commissioning

7.1 Inspection before Commissioning
